INTERNET TELEPHONY has been the VoIP authority since 1998.

The Sigma Residential Voice Service Package is a robust OSS service management solution that is pre-configured to define, provision and maintain IP-based voice services on any broadband network. The service package encapsulates the voice services domain expertise and best practices that Sigma has gained from working closely on over 20 VoIP operator deployments worldwide.

“INTERNET TELEPHONY’s Product of the Year awards honour the leading companies and achievements in our industry. We are extremely proud of this award because it further validates our global leadership in the OSS industry and in this particular segment,” said Tim Spencer, President and Chief Operating Officer for Sigma Systems. “With the Sigma Residential Voice Service Package, CSPs realise significant business benefits while achieving the highest levels of technical and service excellence. Our solution makes it possible to significantly lower implementation times, costs and risks, ensures accurate order management and provisioning operations, enables subscriber self-care, increases revenue opportunities and reduces churn.”

The Sigma Residential Voice Service Package makes it possible to quickly optimise and automate end-to-end operational processes for voice services. Service providers can cost-effectively scale to support millions of subscribers. As well, they can rapidly create new bundles of residential services, including voice service, voice mail and call features. When it is time to fulfil orders, the underlying Sigma Service Management Platform supports shorter order intervals, dramatic reductions in order fallout and faster problem resolution. The end result is that voice service offerings are maximised for customer satisfaction, increased revenue and reduced operational costs.

“Sigma Systems has proven they are committed to quality and excellence while addressing real needs in the marketplace. INTERNET TELEPHONY is pleased to grant a 2007 Product of the Year Award to their Sigma Residential Voice Service Package,” said Rich Tehrani, TMC President and Editor-in-Chief of INTERNET TELEPHONY magazine. “We’re proud to honour their hard work and accomplishments and look forward to more innovative solutions from Sigma Systems in the future.”
